Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575T-5.0 is a step-down (buck) switching voltage regulator manufactured by Texas Instruments (formerly National Semiconductor).  

### **Specifications:**  
- **Output Voltage:** Fixed 5.0V  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220-5 (Through-Hole)  
- **Regulation Type:** PWM (Pulse Width Modulation)  

### **Descriptions and Features:**  
- **Simple and Easy to Use:** Requires minimal external components.  
- **Fixed Output Voltage:** Eliminates the need for external feedback resistors.  
- **Internal Frequency Compensation:** Reduces external component count.  
- **Thermal Shutdown and Current Limit Protection:** Enhances reliability.  
- **Low Power Standby Mode:** Consumes minimal current in shutdown mode.  
- **Wide Input Voltage Range:** Suitable for automotive, industrial, and battery-powered applications.  
- **Stable with Low-ESR Capacitors:** Works well with ceramic or electrolytic capacitors.  

This regulator is commonly used in power supply designs where a stable 5V output is required from a higher input voltage source.
